Math::BigInt module in Perl provides objects that represent integers with arbitrary precision and overloaded arithmetical operators.
from_bin() method of Math::BigInt module is used to convert the binary number passed as input to its corresponding decimal number.
Syntax: Math::BigInt->from_bin()
Parameter: input binary number to be converted
Returns: a corresponding decimal number of the passed binary number
Example 1:
perl
#!/usr/bin/perl # Import Math::BigInt module use Math::BigInt;
# Converting from binary to decimal $x = Math::BigInt->from_bin( "110100" );
print ( "$x\n" );
# Converting from binary to decimal $x = Math::BigInt->from_bin( "0b11001000" );
print ( "$x\n" );
|
Output:
52 200
Example 2:
perl
#!/usr/bin/perl # Import Math::BigInt module use Math::BigInt;
# Converting from binary to decimal $x = Math::BigInt->from_bin( "-110100" );
print ( "$x\n" );
# Converting from binary to decimal $x = Math::BigInt->from_bin( "-0b11001000" );
print ( "$x\n" );
|
Output:
-52 -200
